Hydroxypropylmethylcellulose
Cold water quick-dissolving hydroxypropyl methyl cellulose HPMC is the surface of cellulose ether that is treated with glyoxal under certain temperature and PH conditions. After this treatment, the cellulose ether is put into neutral cold water. It only disperses in the medium without swelling and produces viscosity, which can delay the swelling effect. At this time, the aqueous solution is stirred for 5-10 minutes or when the solution environment (PH value) is adjusted to alkaline, the cellulose ether begins to swell. Viscosity, this type of surface treatment is usually referred to as the instant type.

Application field
1. Cement mortar: improve the dispersion of cement-sand, greatly improve the plasticity and water retention of mortar, have the effect of preventing cracks, and can enhance the strength of cement.
2. Tile cement: Improve the plasticity and water retention of the pressed tile mortar, improve the adhesive force of the tile and prevent powdering.
3. Coating of asbestos and other refractory materials: as a suspension safety agent, fluidity improver, and also improve the adhesion to the substrate.
4. Gypsum coagulating slurry: improve water retention and processability, and improve the adhesion to the substrate.
5. Joint cement: added to joint cement for gypsum board to improve fluidity and water retention.
6. Latex putty: Improve the fluidity and water retention of putty based on resin latex.
7. Stucco: As a paste to replace natural products, it can improve water retention and improve the adhesion to the substrate.
8. Paint: As a plasticizer of latex paint, it has an effect on improving the operation performance and fluidity of paint and putty powder.
9. Spray coating: It has a good effect on preventing the cement or latex spraying from only material filler sinking, improving fluidity and spray pattern.
Packaging and Storage
Packing: plastic paper bag for external use, PVC plastic bag for internal use, net weight 20KG or 25KG per bag.
Storage: rain and sun protection, fire and moisture protection, closed ventilation.
